Questions & Answers

2 Customer Questions

I have gone through several spray bottles that will spray enough for one horse and then quit spraying. These bottles had been working fine before. What is the best way to apply this?

Answer by Chewy • Jun 02, 2022
This gallon jug does not come with an applicator. It is recommended to apply with pressure sprayer or sponge it on horses. Mix Repel-X Pe Emulsifiable Fly Spray with water at proper dilution. First, put the required amount of Repel-X pe Emulsifiable Fly Spray into sprayer or mixing container. Then add water according to directions and mix thoroughly before using.

Can this be used on dogs or cats

Answer by Chewy • Jul 30, 2025

The best fly spray ever!

I have used Repel X for more years than I can count. It kills all those annoying flies, gnats, horse flies and will drop a wasp on contact! It also smells good,

I have used Repel X for more years than I can count. It kills all those annoying flies, gnats, horse flies and will drop a wasp on contact! It also smells good, and I even mist in on myself to keep the deer flies off me! I highly recommend it for anyone who has horses.

Lid was broken upon arrival

Unfortunately when this showed up the lid was broken. As a concentrate it’ll take me a bit of time to use, so I’ll have to find a solution in the meantime. May need

1 gallon of concentrate makes 5 gallons

Cost-effective doing the math. Strong enough to repel flies well.

Easy to use

Big jugs of fly spray can be difficult to pour and I love how highly concentrated this fly spray is. You can make it as strong or as weak as you want and surprise

Flyspray

This flyspray works. I have tried many others with no luck. I buy a one gallon bottle to save some $$. My order arrived quickly and was packed perfectly.
